Pressure Drum Massage Palm Cup , Sputum Remover for The Inability to Expectoration and Burping Toddler Digest Helper Infant Phlegm Sputum ，Also suitable for adults (Transparent)

Works great on my niche zero coffee grinder

This item is a food grade silicone Palm cup BUT I had seen someone review saying it would be perfect for a bellows on a Niche Zero Grinder. At little cost I am able to say with confidence that it worked brilliantly for that!I love my Niche Zero but no grinder is Zero and franckly the Zero is no exception but with this it really does pum out that last little bit which is about 0.1 - 0.2 gram coffee grinds.I love it and recommend fully!

Great item! Purchased for my Niche Coffee grinder to blow out the last few grams of grind. Excellent

I bought this to use on my Niche single doser grinder. It's ideal to puff out the retained grinds.Not what it was designed for but suits the purpose very well and many coffee aficionados use it.Somewhat expensive for what it is though

as always brilliant service. Fantastic prices could not fault them. Thank you very much

Brilliant product used it for my 4 month old who has problems with her secretions

Oddly satisfying to hold and have no idea as to its effectiveness as to its intended function. I purchased this to aide with 'pop-corning' and as a bellows for a Niche Zero coffee grinder - it performs great in this role.
